To compare the use of interdental brushes to a periodontal probe in assessing marginal bleeding, in natural gingivitis.
Sixty-four consecutive volunteers presenting with gingival inflammation were recruited at their semi-annual recall appointments for this study. All had ≥50% papillary height and no pocketing that exceeded 4 mm. Contra-lateral quadrants (1 & 3 or 2 & 4) were randomly tested for bleeding with one pass-through with an interdental brush or with a periodontal probe inserted 2 mm into the gingival sulcus. The presence or absence of both bleeding and plaque were then recorded. Correlation coefficients were calculated for the interdental brushes and the periodontal probe, and the plaque and bleeding scores.
The periodontal probe and the interdental brushes showed mean average bleeding scores of 47.39% and 45.74% respectively. The correlation coefficient for the two methods was 0.73 (P < 0.0001). No correlation between plaque and bleeding was found.
Interdental brushes can be considered a valid alternative to a periodontal probe in assessing marginal bleeding in gingivitis patients. An interdental brush, sized correctly for each interdental space, is easy to handle, atraumatic to the papillae and will allow gingivitis patients to monitor their own progress, while at the same time performing a beneficial oral hygiene procedure and removing any interdental plaque present.
比较使用牙间刷和牙周探针评估边缘性出血在自然性牙龈炎中的效果。
本研究共招募了 64 名连续的志愿者，他们在半年的复诊时因牙龈炎症而就诊。所有患者的牙乳头高度均≥50%，且无超过 4mm 的牙周袋。将每侧的（1 区和 3 区或 2 区和 4 区）随机用牙间刷或牙周探针探测 2 次，评估牙龈出血情况。记录两次是否均有出血和菌斑。计算牙间刷和牙周探针、菌斑和出血评分之间的相关系数。
牙周探针和牙间刷的平均出血评分分别为 47.39%和 45.74%。两种方法的相关系数为 0.73（P<0.0001）。菌斑与出血之间无相关性。
牙间刷可作为评估牙龈炎患者边缘性出血的牙周探针的有效替代方法。对于每个牙间隙，选择尺寸合适的牙间刷，使用方便，对牙乳头无创伤，能让牙龈炎患者监测自身的进展，同时进行有益的口腔卫生护理并去除任何存在的牙间隙菌斑。
